More Information (under review)

The Project is part of the POL science plan and aims to observe sediment transport dynamics within the Dee Estuary. As part of the POL Coastal Observatory an X-Band radar has been deployed at Hilbre Island to monitor bathymetric changes at the mouth of the Dee Estuary. The study will also make a set of marine in-situ observations which are focused on studying the small scale processes, turbulence and SPM resuspension. Understanding these processes is important to predict the large scale variability. Three-dimensional numerical modelling will be used to help interpret the dynamics within the Estuary. The project will also study air-sea interaction and exchanges of momentum at the sea surface and sea-bed. The use of the NERC Aircraft will be of great advantage in giving a synoptic view of the SPM/CDOM and chlorophyll distributions within the Estuary, as well as providing us with high-resolution bathymetry of the intertidal area. The overlapping aerial photographs will also give information about wave refraction over this area: if the wind speed is sufficiently high they will give white cap coverage and the speed of propagation of the breaking wave fronts.
